Entering your License key
Automatic updates are important for your security. ESET NOD32 Antivirus will only receive updates once activated using your License Key.
If you did not enter your License Key after installation, your product will not be activated. You can change your license in the main program window. To do so, click Help and support > Activate License and enter the license data you received with your ESET security product into the Product activation window.
When entering your License key, it is important to type it exactly as it is written:
•Your License Key is a unique string in the format XXXX-XXXX-XXXX-XXXX-XXXX which is used for identification of the the license owner and activation of the license.
We recommend that you copy and past your License Key from your registration email to ensure accuracy.
